What size coax should I have from the 450-d radio to the Dentron tuner running just 100 watts?

I have a 2 foot jumper that says Rg-58 c/u  Mil-C17  50 Ohm. Is this coax sufficient for my set up?

Cable is smaller than a pencil.

Thank you  KG5R??

For a 100 w radio, and jumper to tuner (or outboard watt / SWR meter) the RBG-58 would be fine.  I use
RG-8X for all of my jumpers.  That is slightly larger at 0.240" dia.  It is nice and flexible, too.

Dentron Super Tuner?  I have used those and love them.  Used to use one at a club station.  Great tuner!

Yes they are. Mine is a Junior Monitor. Only rated to 300 watts.

The other day I used it on a gum rapper and a pair of my shorts both came out 1:1

The RG-58 will do just fine.

FWIW, my RG-8 feedline transitions to RG-58 at the antenna disconnect switch.

Yep that is fine

pre-amp I use RG58x

i use 2 dentron tuners

an MT-2000A modified with a 1:1 balun on the input and then floated for a true balanced line tuner to 600 ohm ladder line to a 160 meter skywire

and an MT-3000A to RG213 coax to an 80/40/20 fan dipole that I tune to all bands except 160 including 6 meters.

Dentron tuners are great

in fact today I cut up some RG58X and some RG213 and made some short cables for the shack

PS. I paid $75 each for my 2 Dentrons.
